Size reduction with Planetary Ball Mills

2010-7-5  Planetary Ball Mill. The direction of movement of the sun wheel is op-posite to that of the grinding jars in the ratio 1:-2 (or 1:-2.5 or 1:-3). The grinding balls in the grinding jars are subjected to superimposed rotational movements, which cause the so-called Coriolis forces. The difference in speeds between the balls and grinding jars ...
